IMPROVED yHOSE-COUPLING.

Specification forming part of Letters Patent No. 22,166, dated November30, 1858.

To @ZZ whom t may concern:

Ile it known that I, JAMES C. COOKE, of Middletown, in the county ofMiddlesex and State of Connecticut, have invented a new and ImprovedCoupling for I-Iose or other Like Purposes; and I do hereby declare thatthe following is a full, and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, which make a part of this specification.

My invention consists in providing each part or half of the couplingwith both male and female flanges or parts that interlock each other,arranged and applied in such a manner that either half of one couplingwill readily match or unite with either half of any other coupling, andthus prevent the necessity'of ever changing ends with the length of hoseor other article upon which the coupling is placed or used, as is oftenthe case with the ordinary coupling having one half provided with a maleand the other half provided with a female part only.

My invention further consists in providing my coupling with al taperedpart upon which the hose is to be fastened, the end being bcvelcd, andwit-h a tapering ringor band screwed or otherwise fastened to thecoupling, which ring or band is made large enough to admit and at thesame time hold firmly when in its proper place the thickness of the hosebetween its inner surface and the outer surface of the tapered part ofthe coupling, which band is further provided with a rim or projectionupon its inner side and at or near the end, which shall press the hoseagainst the beveled part of the coupling, at the same time bringing theinner surfaces of the hose and coupling on or nearly on a line with eachother.

Figure l is a side elevation showing the parts together and placed readyto be locked, and with the hose attached to one-half. Fig. 2 is a planor end view showing the form and position ol' the flanges or male andfemale locking parts and the packing. Fig. 3 is a section of one-half ofthe coupling without the band cut through at s s, Fig. 2, showing themale locking parts, packing, tapered and beveled parts, (te. Fig. et isa section of one-half of the coupling and band cut through at w tu, Fig.2, and showing the female locking parts,

packing, tapered and beveled parts vof the coupling, space for the hose,the rim or projection upon the band, tbe.

I make my coupling of any suitable material, leaving thc insidestraight, or nearly so, as seen in Figs. 3 and 4. Upon one end of eachhalf I make one or more female parts, as at a a, Figs. I, 2, and 4.These female parts a d are so constructed and arranged upon the end ofeach half of the coupling that in placing the two halves of the couplingtogether the female parts a a of each half pass into the space li (seenin Fig. 2) between a corresponding female part ct and the male part cupon another halt'. These female parts ct a project beyond the face ofthe coupling, as will be seen in Figs. I and I also place upon the sameend with the female parts tt to a corresponding number of male parts cc, Figs. l, 2, and 3. These male parts c c are so arranged and placedthat when the two halves of the coupling are placed together, as beforedescribed and seen in Fig. l, the male part c upon one half ol' thecoupling comes opposite a corresponding male part c, and upon a linewith the groove d of the female part a of the other half, as seen `inFig. l. rllhen by turning the halves of t-he coupling in opposite directions, as shown bythe arrows in Fig. l, the male parts c e ol' cachhalf enter the grooves d d ol' the female parts (t a of the other halfof the coupling. These male parts c c and the grooves d tl I maketapering upon one side and to correspond with ,each other, as seen inFig. l, (the taper ol' the grooves being shown by dotted line,) so thatin turning the two halves togo-ther, as before described, the two halvesshall bind together and make a substantial joint, and when necessary Iplace in the face of each half a ring of packing of leather or othersuitable material, as seen at c, Figs. 2, 3, and 4.

The indentatious ff are for the purpose of applying a wrench, and may bemade either in that form, or projections may be placed in their stead,as maybe thought best or desired.

I make the other end of my coupling tapering for a suitable distance, asseen at g g, Figs. 3 and 4, and beyond the tapering part I place a screw7L. Then by placing the hose upon this tapering part and passing thetapering ring or bandi over the hoseit will be apparent that as the bandt' is screwed onto the Gilplillg the tapering Qiitaees of bhe couplingand band will be drawn nearer together, thus leaving (when the bandisturned to its place, as seen in Fig. 4) only space enough between themfor the hose, and at the same time the projection j upon the band 'L' ismade to press the hose rmly upon the beveled part 7s of the coupling,thus holding the hose securely in its place, and at the same timebringing the inner surfaces of the hose and coupling upon a line, ornearly so.

I do not claim anges or locking parts having one half of the couplingprovided with a male and the other half a female part, as I am awarethat such is not new. Neither do I claim, broadly,.making both halves0ly lliy couplingvalike; but

What I claim as my invention',` and desire to secure by Let-ters Patent,'is-Y p The female parts a a., in combination with the male parts e c,arranged and made to op erate substantially for the purpose hereinspecified.

Dated at Middletown the 9th day of October, A. D. 1858.
